I have a light-hearted exegesis on political philosophy over at Intellectual Conservative. A sample:
I'm having computer troubles - like everyone else - and that got me thinking about politics. In the political vernacular, "PC" is shorthand for "politically correct" (the hyper-sensitive self-censorship expected of normal people by America's self-appointed diversity police), but another PC, the personal computer, contains far more insight into modern politics.
Let's start with origins. The computer's predecessor was the trusty old calculator. The calculator pretty much did what you might have been able to do yourself, but did it faster, more efficiently and with less prospect of error. That's also a fine prescription for good government. In the limited-government scheme of the American Founders, government exists to do those things citizens can't do efficiently on their own.
Naturally, I think the whole politics-by-analogy article is worth a read.
